ARTEMUS N. HADLEY, OF INDIANAPOLIS, INDIANA.

SHOCK-LIFTER.

T all whom it may concern:

Be it known that I, ARTEMUS N. HADLEY, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and .useful Improvements in Shock-Lifters, of

which the following is a specification.

In the handling of a corn cro it is desirable that entire shocks may be ifted bodily from the field to the wagon in order that they may be readily transferred to the shredder.

The object of my present invention is to provide a device by means of which an entire shock may be engaged in such a manner that it may be lifted bodily by any suitable derrick or crane, such for instance, as that shown in my pending application, Serial No. 189,618.

The accompanying drawings illustrate my invention.

Figure 1, is a plan; Fig. 2, a side elevation; Fig. 3, a detailed plan of a portion of the device; Fig. 4, a front elevation of the members shown in Fig. 3; Fig. 5, a section on line 5 5 of Fig. 3, Fig. 6, a section on line 6 6 of Fig.

5; Fig. 7, a section on line 7 7 of Fig. 5; Fig. 8, a detailed side elevation of the side opposite to that shown in Fig. 5, and on a somewhat smaller scale, and Fig. 9, a detail of a modification In the drawings 10, indicates a head 1n which is journaled a transverse shaft 11 to which is secured a plurality of shock entering teeth 12, each of said teeth being secured to the shaft 11 by means of a suitable clamping head 13.

Journaled in head 10, at right angles to shaft 11, and extending to the rear a suitable distance, is a hollow handle member 14 which, at its rear end, is provided with a transverse handle bar 15. The forward end of the member 14 carries a head 16, within which are pivoted two dogs 17, the outer ends of which are adapted to engage teeth 18 formed upon the forward end of the winding drum 19 journaled on the forward end of the handle member 14. The dogs 17 are nor mally held in engagement with the teeth 18 by means of a light spring 20, and said dogs may be retracted from engagement with teeth 18 by means of the rod 21 which extends through the adjacent over-lapping ends of the dogs 17 and through the handle member 14 to a point adjacent the handle bar 15 Specification of Letters Patent.

Serial No. 262,841.

where said rod is attached to the operating lever 22.

Secured to each end of shaft 11 beyond teeth 12, is a rearwardly projecting arm 25, which at its rear end carries an upwardly projecting pin 26 upon which is pivoted a box 27.

Passing through and secured to each box 27 is a forwardly extending shock embracing arm 28 which is thus adapted to swing upon the vertical pin 26 and to be rotated about the shaft 11 by reason of the movement of arm 25 therewith. Extending from drum 19 to each arm 28 at a point in front of the ivot pin 26 is a cable 30, by means of whic the two arms 28 may be brou ht toward each other as indicated in dotted ines in Fig. 1.

The weight of the structure is supported primarily by means of a rope 31, the ends of which are attached to shaft 11 near its outer ends, and the bight of which is adapted to be received in the ring 32 of the snatch block 33. The bight of the rope 34 is also attached to the ring 32 and each end of said rope is passed through a snatch-block 35, and from thence to the rear end of one or the other of the arms 28. The snatch-blocks 35 are attached to the shaft 1 1 at the point in front of its axis, so that any pull upon these blocks will tend to hold the outer ends of the teeth12 up.

Secured to the shaft 11 with its arms straddling the bearing or head 10 is a yoke 40 which is provided with a down turned portion having a plurality of pawl receiving notches 41 therein, any one of which is adapted to receive the end of the sliding pawl 42 mounted in the body 10 so as to slide transversely with relation to the hollow handle member 14, being normally urged into one of the notches 41 by means of a light spring 43. The pawl 42 has on its upper surface a notch 44 terminating in shoulder 45 adapted to be engaged by any one of a series of In s 46 carried by a collar 47 secured to the ho low handle member 14, arrangement being such that rotation of the hollow handle member in the direction indicated by the arrow in Fig 6 (which is the direction of rotation necessary for winding up the Windlass drum so as to bring the arms 28 together) the lugs 46 will pass into notch 44, engage shoulder 45, and retract pawl 42, but reverse rotation of the handle member is prevented by engagement of the adjacent lug 46 with the top of the pawl 42. In operation the grapple described may be mentioned pending application which can be used to force the grapple prongs 12 of the grapple into the shock if desired. For this purpose I sleeve upon the hollow handle member 14, between a pair of collars 50, a hanging finger 51 adapted to be engaged by a member 52, shown by dotted lines, carried by the derrick structure 53, said structure being clearly illustrated by means of dotted lines to indicate the adjacent supporting wheel thereof. For convenience, member 52 of the derrick should carry a pair of upright pins 54 between which the handle member 14 may be passed.

In operation the grapple is supported from the snatch-block 33 .by a cable 31 and the shock-embracing arms 28 normally are eX- tended as shown in Fig; 1. The shaft 11 is also swun so that the prongs 12 will lie substantial y horizontally being held in that position by means of a pawl 42. The prongs 12 are supported a suitable distance from the ground and substantially parallel therewith andby exerting sufficient force upon the structure these prongs may be driven transversely into a shock preferably at a point near the butt. The operator then turns the handle member 14 in the direction indicated by the arrow in Fig. 6 whereupon cables 30 are wound upon the drum 19 and the arms 28 brought together so as to embrace the shock, as indicated in dotted lines in Fig. 1. During this operation the pawl 42 is repeatedly withdrawn from engagement with yoke 40 by the action of successive locks 46 but, as the shock still rests upon the ground there is no tendency to shift the shaft 11 within the head 10. As the arms 28 are drawn together the slight slack in the cables 34 is taken up and the weight of the structure thereupon transferred from cable 31 to cable 34 so that there is a tendency to return the arms 28 to initial or open position, this tendency being resisted, however, by a cable 30 which has been wound upon the drum 19. As soon as a lifting pull is exerted upon the snatch-blocks 33 the entire shock may be lifted and transferred to any desired point of deposit and when this point of deposit is reached the operator turns handle member 14 slightly in the direction indicated by the arrow in Fig. 6 so as to retract pawl 42 from engagement with yoke 40 thus releasing shaft 11 so that it, together with shock embracing arms 28 and the prongs 12, may be turned in the position indicated by dotted lines in Fig. 2. Simultaneously with the withdrawal of the pawl 42, as described, the operator will swing the catch arm 22 so as to withdraw the clutch members 17 from engagement with the drum 19 and, as the weight of the structure together with the shock, is supported by cables 34, said cables operated to automatically swing arms 28 to an open position and the shock is, therefore turned upon its side and dropped off of the prongs 12.

As soon as the weight of the shock is withdrawn from the prongs 12, however, the weight of the cable structure, acting as it does upon cable 34 and through it upon the snatch-blocks 35 which are forward of the aXis of shaft 11, automatically swings the prongs 12 upward to normal position.
